YLT(i)
13 and we in regard to the unmeasured things will not boast ourselves, but after the measure of the line that the God of measure did appoint to us—to reach even unto you;
14 for not as not reaching to you do we stretch ourselves overmuch, for even unto you did we come in the good news of the Christ,
15 not boasting of the things not measured, in other men's labours, and having hope—your faith increasing—in you to be enlarged, according to our line—into abundance,
16 in the places beyond you to proclaim good news, not in another's line in regard to the things made ready, to boast;
17 and he who is boasting—in the Lord let him boast;
18 for not he who is commending himself is approved, but he whom the Lord doth commend.
